Description:

TECHNICAL FIELD

The present invention relates to a hair growth inhibitor such as a hair development inhibitor containing a specific herb or its extract, as an active ingredient, and external application compositions such as a cosmetic, quasi-drug or skin lotion, particularly a cosmetic composition, containing the same.

BACKGROUND ART

The head hair or body hair of the human body inherently biologically protects important body organs such as head, chest, limbs, but means of protection such as clothing, protective means have appeared and are used and developed by human beings, the protective function of body hair is becoming no longer important.

Further, in general, while abundant head hair is still desirable, in recent years there has been an increasing trend favoring no body hair, particularly on the limbs, in terms of aesthetic appearance. Therefore, various hair removing methods have been developed and utilized. Specifically, mechanical removal methods using a shavers, hair depilators, etc., methods of using hair depilatory agents to remove body hair from their roots, methods of removal of body hair by chemical action using hair removal agents, etc. may be mentioned.

However, these hair removal methods are sometimes accompanied with physical or chemical irritation to the skin. Further, while there is some difference depending on the hair removal methods, there are limits to the sustainability of the hair removal effect. Therefore, the hair removal treatment must be repeated after the elapse of a certain time. Reduction of the hair removal treatment work is therefore desired.

As mentioned above, the development of technology, for example, for inhibiting the growth or removal of, body hair providing less irritation on the skin and capable of lightening the burden of hair removal treatment work is desired. Under these circumstances, the present inventors engaged in intensive research on the hair growth inhibiting abilities of various herbs and found that specific herbs have hair growth inhibiting capability. As a result, we succeeded in the development of the hair growth inhibitor according to the present invention and cosmetics and external application compositions such as a cosmetic composition containing the same.

DISCLOSURE OF INVENTION

Accordingly, the object of the present invention is to provide a hair growth inhibitor capable of effectively inhibiting the growth or development of body hair and reduce the number of times of hair removal treatment and external application compositions such as a cosmetic composition containing the same. In particular, the present invention found that specific herbs or the extracts thereof act directly on hair matrix cells and dermal papilla cells to provide a superior hair growth inhibiting effect and have high safety over long term use and provides a hair growth inhibitor having one of these herbs or the extracts thereof as an active ingredient and external application compositions such as a cosmetic composition containing the same.

In accordance with the present invention, there are provided a hair growth inhibitor comprising, as an active ingredient, at least one herb selected from the group consisting of phellodendron bark, houttuynia, rice bran, mulberry tree, bark, Japanese coptis, thyme, peach seed, nettle, calendula, wild rose and balm mint or the extract thereof and an external application composition such as a cosmetic composition containing the same.

Hair Growth Inhibiting Performance Evaluation Test

An evaluation test was performed using the body hair cells of rats to evaluate the hair growth inhibiting performance. Details of the test are given below. Note that rat body hair cells were taken with reference to the method described in Japanese Unexamined Patent Publication (Kokai) No. 10-265341.

Dorsal skin was taken from newborn (3 to 4 day old) rats and immersed overnight in 0.25% trypsin-containing PBS (including 0.02% EDTA, same below) at 4° C.

After immersion, the dermis layer and the epidermis layer of the dorsal skin were separated, the dermis layer was cut by scissors, then steeped at 37° C. for 35 minutes in a Ham's F12 medium containing 0.35% collagenase. After permeation, this was pipetted until clump-like masses were no longer seen in the collagenase reaction product, then Ham's F12 medium containing DNase (10000 units) was added and allowed to stand for 5 minutes.

After standing, the suspension obtained was further pipetted, then filtered by a Nylon mesh (Nytex 157 mesh), then the suspension was diluted by PBS (−) and centrifuged (4° C., 400 rpm, 5 minutes). After centrifuging, the supernatant was removed and PBS (−) was added to the residue to cause resuspension, then the resultant suspension was further centrifuged [(4° C., 400 rpm, 5 minutes)×3 times]. The residue obtained from this centrifugation operation was the follicles in the dorsal skin of rats to thereby prepare the follicles.

(2) Preparation of Follicular Epithelial Cells

0.25% trypsin-containing PBS (−) was added to the follicles obtained by the above operation. The cell suspension was then incubated at 37° C. for 5 minutes. After the end of the incubation, equal amounts of fetal bovine serum (FBS) and Ham's F12 medium were added, then the cell suspension was filtered by a cell strainer (100 μm, made by Nalgene). After filtration, the filtrate was centrifuged (4° C., 1500 rpm, 5 minutes). The supernatant was removed from the filtrate after centrifugation to obtain the desired follicular epithelial cells as the residue.

2. Preculturing of Follicular Epithelial Cells

To remove, as much as possible, the fibroblasts contained in, the follicular epithelial cells obtained above were precultured. This procedure will be explained below.

The number of cells of the follicular epithelial cells obtained was calculated by a hemocytometry plate and adjusted by an FAD medium to give a concentration of 2.5×105 cells/ml. The above cells were inoculated in a 75 cm2 flask coated with I-type collagen and cultured overnight at 37° C. in 5% CO2. After culturing, the resultant product was washed two times with 10 ml of PBS (−), 2 ml of 0.25% trypsin-containing PBS (−1) was added, then the resultant cells were incubated at 37° C. in 5% CO2 for 4 minutes. Next, 2 ml of fetal bovine serum (FBS) was added, the resultant mixture was lightly shaken, then the supernatant was separated. This removed the fibroblasts contained therein.

The herb extracts obtained from Production Examples 1 to 6 were adjusted by DMSO to give 0.2% solutions. Further, as a control, a 70% ethanol extract of coriander seeds (Coriandrum sativum L.) with a known hair development effect was adjusted by DMSO to give a 0.2% solution and diluted by KGM medium to prepare a test sample for a medium for use for evaluation.

2. Preparation of Control Medium

KGM medium was used for evaluation as a control.

3. Assay of Substance to be Tested

The rate of intermixture of fibroblasts (FB intermixture rate) of a culturing flask inoculated with the follicular epithelial cells obtained by the above operation was measured (×300, 5 observation fields). Samples with FB intermixture rates of 3% or more were excluded from the coverage of the assay. The follicular epithelial cells were washed two times by 10 ml of PBS (−), 0.25% trypsin-containing PBS (−) was added, then the result was shaken at 37° C. at 20 rpm for 5 minutes.

The suspension formed by the above shaking operation was filtered by a cell strainer (100 μm, made by Nalgene). After filtration, 50 ml was placed in a centrifugation tube, the number of live cells in the suspension was calculated by a hemocytometry plate, then KGM medium was added to the suspension to adjust it to a cell concentration of 5.0×104 cells/ml. Next, the adjusted suspension was inoculated in a 96-well plate (I-type collagen coated plate, made by Falcon) in an amount of 0.2 ml/well (1.0×104 cells/well), then cultured at 37° C. in 5% CO2 for one day. The media were exchanged in the control medium (KGM medium) and test samples, then the resultant mixtures were incubated at 37° C. in 5% CO2 for two days. After this, the cell proliferation was measured by the following method. The results are shown in Table I.

C. Measurement of Cell Proliferation

A 1/10 amount of alamar blue (made by Alamar Bioscience) was added based upon the culturing amount (volume) and the resultant mixture was incubated at 37° C. (5% CO2) for 6 hours. After incubation, the absorbances of the system at 595 nm and 570 nm were measured using a micro plate reader (made by Bio RAD).

D. Judgment of Results

In the two days after the exchange of the medium, the number of the rat follicular epithelial cells in the control KGM medium proliferated about two-fold. Using the degree of cell proliferation in the control medium as 100%, the degree of cell proliferation at the time of addition of each sample was measured. The difference between the former and the latter was calculated and used as the cell proliferation inhibiting rate.

As is clear from the results of the above hair growth inhibiting performance evaluation tests, in the evaluation tests based on rat follicular epithelial cells using the herb extracts of the active ingredients of the hair growth inhibitor of the present invention, the extracts of Production Examples 1 to 6 were observed to have hair growth inhibiting effects

C3H Mouse Hair Development Inhibiting Test

The dorsal hairs of groups of three C3H mice of eight weeks age were shaved off by electrical shears over 2×4 cm2 areas, then surface hair removal cream (Shiseido: Devenu) was used for treatment to remove surface hair. The test samples were coated over the surface hair removal portions once a day in amounts of 100 μl a time over 18 days. The test samples were dissolved in a solvent (100% ethanol). For the control group, only the solvent was coated.

The hair recovery of the surface hair-removal portions 10 days and 18 days after coating were scored. The hair development inhibiting effects were compared with the control growth for the scores 10 days after coating. Scores of points lower than the control growth were evaluated as indicating there were hair developing inhibiting effects. The growth inhibiting effects were evaluated by finding the difference of the scores for 10 days and 18 days after coating and judging differences smaller than the difference of the control group as growth inhibiting effects. The concentrations of the test samples and the results of evaluation are shown in Table III.
